Antibacterial, mildew-proof, corrosion-resistant, fire-proof, high-pressure decorative board and production method thereof

Abstract

The invention relates to a decorative board, in particular to an antibacterial, mould proof, corrosion-resistant and fireproof high pressure decorative sheet and a production method thereof. The decorative sheet comprises a fireproof base plate, a buffer layer is arranged on the fireproof base plate, a tack coat is arranged on the buffer layer, a decorative layer is arranged on the tack coat and the fireproof base plate is prepared from multiple layers of glass fiber mat dipped by a thermosetting alcohol soluble phenolic resin; the buffer layer is prepared from brown paper dipped by the thermosetting alcohol soluble phenolic resin; the decorative layer is prepared from decorative paper coated by an epoxy resin which is added with an antibacterial agent and has a dual curing system of thermosetting and photocuring. The decorative sheet has the advantages of waterproofing, humidity resistance, impact resistance and good dimensional stability; the surface of the decorative sheet has the advantages of corrosion resistance, fouling resistance, abrasion resistance, antibiosis and mould proofing; in addition, the surface of the decorative sheet is easy to clean, does not contain resin containing aldehyde, and has a low burst size of formaldehyde.

Description

technical field [0001] The invention relates to a decorative board, in particular to an antibacterial, mildew-proof, corrosion-resistant, fireproof, high-pressure decorative board and a production method thereof. Background technique [0002] With the improvement of people's living standards, the requirements for aesthetics, functionality, and individuality of decoration are gradually increasing. Interior decoration materials, including countertops, wall panels, and furniture, need to meet appropriate strength, fire resistance, stain resistance, and corrosion resistance. , antibacterial and mildew-proof, low release of formaldehyde harmful to human body, beautiful and practical, etc., to meet the requirements of safety, practicability, and aesthetics of decoration. Therefore, the material requirements for interior decoration materials are gradually increasing. [0003] In recent years, the commonly used interior decoration materials mainly include paint, coating, soft decora...

AI Technical Summary

Problems solved by technology

Most paints and coatings contain volatile solvents such as benzene, toluene and other organic pollutants, which may cause potential harm to the health of users or occupants; wallpapers, wall coverings, etc. are not waterproof, not moisture-proof, easy to fall off when the humidity is high, and easy to mold. , Most of the glue used for pasting is benzene and toluene solutions of rubber adhesives. Volatile solvents are also harmful to the human body; ceramics have no plastic deformation at room temperature and have high compressive strength, but poor tensile strength, bending strength and impact resistance, and are brittle. Fracture; natural stone has high hardness and wear resistance, but has the disadvantages of radioactivity, high permeability, and poor impact resistance; artificial stone uses a lot of resin, and most of them can only be used for countertop decoration; most decorative panels are based on wood or wood derivatives material, after being painted and pasted on the base material, it also has the disadvantages of being not waterproof, fireproof, high pressure resistant, etc.

At present, the widely used high-pressure decorative laminate is produced by impregnating paper (including decorative surface paper and base paper) with thermosetting resin after high temperature and high pressure. It is mainly used for furniture and interior decoration. Divided into light and pitted surfaces, the biggest defect of the above materials is that because this kind of decorative materials and substrates are combustible, they can burn continuously in case of fire, and they are prone to produce a large amount of toxic and suffocating smoke during the combustion process. , Frequent large-scale fire accidents, especially high-rise residential buildings and serious fires in commercial areas have caused serious casualties. People pay more and more attention to the safety of construction and decoration materials. These traditional materials are difficult to meet the needs of decoration.
